ULV mercon for ford 6R80 ???????

[zogg]

I have a 2017 F150 2.7 with the 6R80 six speed transmission. At 57,000 I was going to have a shop flush the transmission. They say they only use Phillips 66 ULV atf for fords. My manual specs LV, not ULV.
Is that ok or should I go elsewhere??

ulv is clearly for the 10 speeds and isn't backwards compatible with the 6 speed, they should know that. That shop is ran by fools that'll damage your transmission.

As far as I know all 6r80's take LV. Triple check your sources before putting ULV in it.

Sounds like you should find a new shop. Also, don't get a machine flush. A drain and fill is what you want.

Edit: Phillips makes most Motorcraft fluids for Ford so there's nothing wrong with that brand, just make sure to use the correct type.

This sounds like the shop has Phillips 66 ULV as their only ATF, probably bulk. Unless Ford issued a TSB to use ULV ATF I would stick with the LV ATF.

1. No flush. You are doing it on schedule pretty much so a pan drop, wipe, and refill is what is needed. At 120K do the filter and another fluid dump and fill.
2. The 6R80 is sped for LV. Use LV.

My suggestion don't use that shop going forward. Recommending the incorrect fluid is unacceptable and it would make me question any other work they do as well.

LV .... Low Viscosity
ULV .... ULTRA Low Viscosity

Like motor oils, use the viscosity that's shown in your owner's manual.
You'll sleep better at night.

No, go to a different shop. ULV is not for the 6R80 at all. Do not flush, drop the pan and change the filter. The flushing doesn't work on these unless they use a heated flushing machine since the thermostatic valve will bypass the cooler.

Dropping the pan on your transmission is a piece of cake. The gasket is reusable and filters are cheap. Use only LV, not ULV. Mercon LV is cheap. Refill will require the engine to be running to get the last 2 quarts back in. Watch the cat converter beside the fill port and tiny dipstick so you don't burn yourself.

If you use ULV The next thing you’ll be buying is a new Tranny Stick with LV and you’ll be happy

Changing the filter is not as important as changing the fluid (if it's worn / dirty) and cleaning the magnet.

I've got an OE 6R80 filter cut open and the filter media is not great, I'd guess maybe a 30-50 micron? I remember being surprised how much daylight was getting through. On the other hand, clean pan and magnets will PULL metal out of suspension 24hrs a day.

I second this. I will add, wear a long, thick rubber grill glove when checking the level. I’ve got a nice manly burn scar on my arm from just brushing against that running cat for a microsecond.
